The SEC posted on its website the proposed new rules to establish a large trader reporting system. The proposal is intended to assist the Commission in identifying and obtaining certain baseline trading information about traders that conduct a substantial amount of trading activity, as measured by volume or market value, in the U.S. securities markets. The proposed large trader reporting system is designed to facilitate the Commission’s ability to assess the impact of large trader activity on the securities markets, to reconstruct trading activity following periods of unusual market volatility, and to analyze significant market events for regulatory purposes. It also should enhance the Commission’s ability to detect and deter fraudulent and manipulative activity and other trading abuses, and should provide the Commission with a valuable source of useful data to study markets and market activity.
